  • Publication number: 20160064554
    Abstract: In a field-effect semiconductor device, alternating first n-type and p-type pillar regions are arranged in the active area. The first n-type pillar regions are in Ohmic contact with the drain metallization. The first p-type pillar regions are in Ohmic contact with the source metallization. An integrated dopant concentration of the first n-type pillar regions substantially matches that of the first p-type pillar regions. A second p-type pillar region is in Ohmic contact with the source metallization, arranged in the peripheral area and has an integrated dopant concentration smaller than that of the first p-type pillar regions divided by a number of the first p-type pillar regions. A second n-type pillar region is arranged between the second p-type pillar region and the first p-type pillar regions, and has an integrated dopant concentration smaller than that of the first n-type pillar regions divided by a number of the first n-type pillar regions.

The peripheral area includes a first edge termination region and a second semiconductor region in Ohmic contact with the drift portions having a second maximum doping of the first conductivity type which lower than the first maximum doping concentration by a factor of ten. The first edge termination region of the second conductivity type adjoins the second semiconductor region and is in Ohmic contact with the source metallization.

  • Patent number: 9070580
    Abstract: A super junction structure is formed in a semiconductor portion of a super junction semiconductor device. The super junction structure includes a compensation structure with a first compensation layer of a first conductivity type and a second compensation layer of a complementary second conductivity type. The compensation structure lines at least sidewall portions of compensation trenches that extend between semiconductor mesas along a vertical direction perpendicular to a first surface of the semiconductor portion. Within the super junction structure and a pedestal layer that may adjoin the super junction structure, a sign of a lateral compensation rate changes along the vertical direction resulting in a local peak of a vertical electric field gradient and to improved avalanche ruggedness.

  • Publication number: 20140327104
    Abstract: A super junction semiconductor device includes a layered compensation structure with an n-type compensation layer and a p-type compensation layer, a dielectric layer facing the p-type layer, and an intermediate layer interposed between the dielectric layer and the p-type compensation layer. The layered compensation structure and the intermediate layer are provided such that when a reverse blocking voltage is applied between the n-type and p-type compensation layers, holes accelerated in the direction of the dielectric layer have insufficient energy to be absorbed and incorporated into the dielectric material. Since the dielectric layer absorbs and incorporates significantly less holes than without the intermediate layer, the breakdown voltage remains stable over a long operation time.

  • Publication number: 20140128648
    Abstract: The present invention relates to a process for hydrocarbon conversion in the presence of an acidic ionic liquid. The hydrocarbon conversion is preferably an isomerization, especially an isomerization of methylcyclopentane (MOP) to cyclohexane. Prior to the hydrocarbon conversion, a hydrogenation is performed, preference being given to hydrogenating benzene to cyclohexane. The cyclohexane obtained in the hydrogenation and/or isomerization is preferably isolated from the process. In a preferred embodiment of the present invention, the hydrogenation is followed and the hydrocarbon conversion, especially the isomerization, is preceded by distillative removal of low boilers, especially C5-C6-alkanes such as cyclopentane or isohexanes, from the hydrocarbon mixture used for hydrocarbon conversion.
